Welcome, my friends! This website is to help those who need help in mathematics topics especially in visualizing it. Topics covered including secondary to tertiary level. Interactive graphs are provided for concept exploration. Please use Mozilla Firefox or Google Chrome to view, do not use Internet Explorer.
Meantime, most of the topics are visualized with Geogebra.
There are more to come in the future. See you around!
A coordinate (x,y) in xy-plane can be written in polar form , where r is the directed distance from (0,0) to (x, y), and is the directed angle formed by the vector <x, y> from the positive side of x-axis:
There are some interesting graphs can be obtained through polar equations, such as
